Background
Belt conveyors are common equipment for material handling that carry and convey material through a moving conveyor belt and to a designated location. However, the conveyer is required to be provided with a conveyer belt speed measuring device for detecting whether the conveyer belt runs at the designed speed, if the running speed of the conveyer belt is abnormal, usually less than the specified speed, the abnormal state of the belt conveyer is shown, for example: the conveyer belt fracture or conveyer belt phenomenon of skidding appear unusually to drive arrangement, cause drive power can't transmit drive drum and drive the conveyer belt operation, consequently prevent that the conveyer belt speed sensor that skids is a very important protection device.
The existing speed measuring device for preventing the sliding of the conveying belt is used for detecting the running of the conveying belt by contacting a return belt conveyor of the conveyor through a special roller, or a detection device is arranged on the side surface of a turnabout drum of the belt conveyor, and the like.
